Description

The invention relates to an openable vehicle roof with a lid which is adjustable between a closed position in a roof opening and an open position in which it is raised at least at its rear edge and at least partially displaced over an adjacent roof section, wherein the lid by means of a drive means displaceable front bearing device along a front guide rail movably mounted and mounted by means of a rear bearing means on the adjacent roof portion and movable along a rear guide rail.

From the DE 10 2008 046 331 A1 is a generic vehicle roof has become known, the cover is moved as a spoiler roof from a roof opening to the rear on the adjacent roof surface. The extension lever of the rear bearing device is fixedly coupled by means of a reduction gear to the taking place via the front bearing means driving the lid, so that when moving the lid in its open position, the distance between the front bearing device and the rear bearing device decreases continuously. When the cover is moved to its rear open position, the distance between the front bearing device and the release lever of the rear bearing device is comparatively small. This small support length can lead to unwanted vibrations of the open lid.

The invention has for its object to provide an aforementioned vehicle roof, which is improved in terms of the aforementioned disadvantage.

This object is achieved in the vehicle roof according to the invention in that the rear bearing device is coupled via a first or front Teilbewegungsweg the lid to the drive means or the front bearing means and a second or rear Teilbewegungsweg the lid of the drive means or the front bearing means uncoupled and fixedly locked on the roof side or on the rear guide rail, and that the drive means on the second or rear part movement path displaces the lid relative to the stationary held rear bearing device.

Advantageous embodiments of the invention are specified in the dependent claims.

In contrast to a fixed coupling between the front and the rear bearing device is thus in the vehicle roof according to the invention, the coupling of the rear bearing means to the drive means or to the driven by the drive means front bearing means of the lid or driven by the drive means cover at a specific point in the opening process the lid interrupted. The location of coupling and uncoupling can be determined with regard to the desired length of the common movement as well as with respect to the position of the locked end position of the rear bearing device with the lid open. Thus, the distance between the front bearing device or the drive device and the rear bearing device is substantially constant over the first movement path, while the distance between the front bearing device or the drive device and the rear bearing device except for the second movement path after releasing the coupling minimal support length decreases.

The adjacent roof section, which is located in such a spoiler roof usually in the vehicle longitudinal direction behind the roof opening, z. B. a solid vehicle roof or a fixed or a movable lid.

The guide rails and the storage facilities of the lid are provided on both sides of the vehicle roof and symmetrically to the roof opening or to the vehicle longitudinal axis. The description is essentially only on the basis of this management and storage facilities on one of the two long sides of the lid.

In a preferred embodiment, a coupling device for coupling and uncoupling of the rear bearing device is provided and the coupling and uncoupling takes place between the coupling device and the drive device or the front bearing device or between the coupling device and the rear bearing device. As a coupling device or part of the coupling device is any tensile and compressive forces and movement transmitting device such. B. a coupling rod or z. B also a correspondingly guided Bowden cable.

The movable drive device is suitably connected via a conventional train-pressure cable with a drive motor, the z. B. can be arranged centrally on the vehicle roof in front of or behind the roof opening. The drive device is connected directly or indirectly to the front bearing device or the lid.

Conveniently, the rear bearing device includes a release lever which is slidably mounted on a cover longitudinal guide of the lid. The cover longitudinal guide is z. B. formed as a guide slot and attached to a side cover carrier or cover frame. Alone the Release lever connects the lid in its rear portion with the rear guide rail, thus lifting the lid over the roof and supports the lid, while it is displaced with the lid to the rear and when it is set against the roof moving lid on the roof side. The deployment lever is preferably mounted slidably and pivotably via a slider on the cover longitudinal guide. As a slider each slidably mounted on the lid longitudinal guide component is called, which also z. B. can represent a carriage or a roller-mounted component.

In a preferred embodiment, it is provided that the deployment lever is slidably mounted on the rear guide rail at least by means of a front slider and a rear slider, which are spaced apart along the guide rail. When the lid is closed, the release lever is in a lowered position, in which the rear slider is disposed on the horizontal longitudinal guide portion of the guide rail and the front slider on a front substantially horizontal guide portion which is opposite to the horizontal longitudinal guide portion at a lower level. Since both sliders are arranged with the lid closed in substantially horizontal portions of the rear guide rail, the release lever provides a secure and firm support of the lid at its rear edge in the vertical or Z-direction, especially when forces attack the lid, which him up from the Pull roof opening or push. The vertical distance between the lower level of the front horizontal guide portion and the horizontal longitudinal guide portion of the rear guide rail and design of the deployment lever are coordinated so that the release lever can perform the required swiveling and lifting movement.

The drive device for adjusting the cover in particular has a drive slide, which is expediently mounted on or adjacent to the front guide rail and parallel to this displaceable. The drive carriage is preferably in adjusting engagement by means of an engagement element in a slotted guide of a link carrier which is connected to the cover and which may be part of the front bearing device of the cover.

Conveniently, the slotted guide includes a driving portion in which the engaging element is arranged on transmitting the transmission of a longitudinal movement on the slide. The driving portion extends substantially perpendicular to the direction of movement of the drive device or the drive carriage. In a front portion of the slotted guide, which is also referred to as a horizontal section, the engagement element is movable relative to the slide carrier in the X or longitudinal direction. Thus, the drive carriage is in the X- or longitudinally substantially stationary lid, such. B. when adjusting the lid in a ventilation position, adjustable.

Basically, "horizontal" means a direction or movement along the roof or roof-side guides, which may or may also follow a curvature of the roof in the longitudinal direction.

If according to a preferred embodiment, the front guide rail in the movement range of the front bearing device in a dry area, especially within a lid seal, and the rear guide rail in the movement range of the rear bearing device in a wet area, in particular outside a lid seal, are arranged, the arrangement of the rear guide rail is not limited to the area of the roof opening. Thus, the arranged behind the roof opening roof section can be used without space limitation for the movement of the rear storage facility. The wet area is that area of the openable roof which is accessible to water and is discharged from the incoming water via water drainage facilities. In contrast, the drying area is separated and sealed, thus extending in particular within a region bounded by a peripheral seal of the lid.

Conveniently, the coupling rod is arranged and guided so that it extends through a partition wall which can be arranged between the dry area and the wet area and has a recess or opening through which the coupling rod extends. A seal can seal the passage of the coupling rod through the recess or opening of the partition wall in this case. The lateral cover longitudinal guide is preferably arranged in the wet area laterally below the side edge region of the cover outside a cover seal. Thus, only the coupling rod must be passed through the opening in the partition.

In any case, the rear guide rail to the front guide rail may be arranged in particular in alignment, so that the required space is minimized at the opening vehicle roof in the transverse direction. However, this can also be deviated from, if special designs are to be provided.

By means of a locking device, the coupling and uncoupling of the coupling device and the roof-side locking of the coupling device controlled or executed. Such a locking device contains z. B. a bar brick and / or control and run-on slopes or the like.

A lid for closing and at least partially releasing the roof opening is any roof element that can take over this function regardless of its shape or design. Such a roof element, for example, a transparent glass lid or plastic lid, may be attached to the frame and bearing parts or molded.

The invention will be explained in more detail with reference to an embodiment of a vehicle roof according to the invention with reference to the drawing. It shows:

An openable vehicle roof 1 a vehicle such. B. a passenger car has a lid 2 on, coming from a closed position in a roof opening 3 liftable (see 1 ) and in a ventilation position is adjustable and from the ventilation position with raised rear edge 4 over one in the vehicle or roof longitudinal direction behind the roof opening 3 adjoining roof section 5 in an open position is movable (see 2 ). Such a roof is also called a spoiler roof. The rear roof section 5 can in principle be formed by a fixed roof or by a movable roof part. The axis and direction designations used in the description such. "Front" and "rear", "top" and "bottom", "outside" and "inside", "horizontal" and "vertical" and "lateral" refer to a three-dimensional vehicle coordinate system.

The lid 2 is on both sides of the roof opening 3 each by means of one under his front 6 arranged front storage facility 7 along a roof side arranged lateral longitudinal guide such. B. a front guide rail 8th and by means of its rear edge 4 associated rear storage facility 9 along a roof side arranged lateral longitudinal guide such. B. a rear guide rail 10 movably and movably mounted.

The front guide rail 8th has an initial section 11 on, from the front end 12 starting has an obliquely rising upward course. With the lid closed 2 (please refer 3 ) is a glider 13 the front storage facility 7 in the beginning section 11 in lowered position near the front end 12 the guide rail 8th arranged.

The rear storage facility 9 has a release lever 14 on (in the 3 to 6 is the release lever 14 shown schematically in triangular form), on the one hand by means of a front slider 15 and a rear slider 16 on the rear guide rail 10 slidably mounted and on the other hand by means of an upper slider 17 along a cover guide 18 sliding and opposite the cover guide 18 is pivotally mounted. The rear guide rail 10 has at its front end a front horizontal guide rail section 19 at a lower level, to which an approximately S-shaped rising intermediate section 20 connecting to the upper level of a longitudinally extending main guide section 21 the rear guide rail 10 enough.

A drive carriage 22 is on a lateral longitudinal track 23 attached to the front guide rail 8th runs longitudinally, z. B. with two sliders 24 and 25 slidably mounted and via a drive cable 26 (please refer 8th ) connected to a drive motor, the z. B. on the vehicle roof centrally behind the roof opening 3 located.

A coupling rod 27 is with the release lever 14 and in particular with the rear glider 16 of the release lever 14 firmly connected and extends from this along the front guide rail 8th forward to the closed lid 2 arranged in a front end position drive carriage 22 , The coupling rod 27 is in particular by means of a locking device 28 on the one hand to the drive carriage 22 coupled, so that it is displaceable by this during its drive movement, and on the other hand from the drive carriage 22 decoupled and can be fixed on the roof side, z. B. at a recess 29 (only in 6 shown) in the front guide rail 8th or on a latch hook 29 ' or the like, so that the drive carriage 22 relative to the dormant coupling rod 27 as well as the likewise resting Ausstellhebel 14 is relocatable.

The front storage facility 7 has a slide holder 30 on, which is attached to the underside of the lid and in particular to a lid carrier and a slotted guide 31 Contains, on which an engaging element 32 of the drive carriage 22 is guided.

The front guide rail 8th is preferably in a dry area 33 of the vehicle roof 1 arranged (see 8th ), which is inside a lid seal 34 extends the cover 2 peripherally seals against the roof and on the lid 2 or attached to the roof. The front storage facility 7 with her glider 13 and the drive carriage 22 move in this dry area 33 , In one of the dry area 33 separated wet area 35 is the rear guide rail 10 arranged and the path of movement of the release lever 14 the rear storage facility 9 as well as the cover guide 18 for the release lever 14 run here. A partition 36 separates the drying area 33 from the wet area 35 and a section of the partition 36 , in the 8th schematically shown as a dotted line, runs in particular in the transverse direction between the front guide rail 8th and the rear guide rail 10 , The partition 36 has a recess or opening 37 on, through which the coupling rod 27 extends through. A seal 38 seals the coupling rod 27 in the recess or opening 37 to the partition 36 down.

Below is the opening of the lid 2 from its closed position ( 3 ) to the fully open position ( 6 ). In the closed position is the lid 2 in the roof opening 3 flush with the surrounding roof surface 5 arranged. This is the front slider 13 lowered at the front end 12 the front guide rail 8th and the engagement element 32 of the drive carriage 22 is in a front horizontal section 39 the slide tour 31 (please refer 3 and 7 ), which extends approximately horizontally and slightly inclined downwards to the rear. The vertical support of the lid 2 at its front area 6 thus takes place substantially over the front horizontal section 39 the slide tour 31 that are on the engaging element 32 of the drive carriage 22 supported substantially vertically.

The release lever 14 supports the lid 2 laterally in the area of its rear edge 4 from. Because the front glider 15 in the front horizontal guide rail section 19 and the rear glider 16 in the rear horizontal main guide section 21 the guide rail 10 are arranged, is the lid 2 at its rear edge 4 securely supported and locked in the vertical or Z direction. The release lever 14 is over the tie rod 27 firmly on the Ausstellschlitten 14 coupled, which in turn is held stationary by the drive motor. Thus, the release lever can 14 at the lid 2 attacking forces that z. B. due to negative pressure of the air flow or shocks, do not move.

For adjusting the lid 2 from its closed position into a ventilation position (movement from the position of the 3 in the position of 4 ) becomes the drive carriage 22 along its longitudinal track 23 moved backwards. At the same time the release lever 14 that over the tie rod 27 on the drive carriage 22 docked to its rear glider 16 shifted to the rear while his front skid 15 from the lower guide rail section 19 and over the intermediate section 20 also in the upper main guide section 21 moves and by this movement the release lever 14 swings up into its upright support position. When pivoting the release lever 14 represents the upper slider 17 about his intervention on the cover guide 18 the lid 2 at its rear edge 4 out.

At the front area 6 of the lid 2 the engagement element moves 32 of the drive carriage 22 in the front horizontal section 39 the slide tour 31 that moves along the path of movement of the engagement element 32 to the longitudinal track 23 of the drive carriage 22 z. B. approaches continuously or curved. Thus, the scenery support 30 slightly raised and thereby in the beginning section 11 the front guide rail 8th moving skid 13 determines the position of the lid 2 also in the X or longitudinal direction, which is slightly shifted to the rear. The lid 2 thus follows at its front 6 the movement of the slider 13 in the front guide rail 8th while at the back end 4 the upper slider 17 of the release lever 14 on the lid guide 18 relative to the lid 2 moved backwards.

To the lid 2 from the in 4 shown ventilation position further to the rear over the adjacent roof section 5 in an open position to adjust, the drive carriage 22 along the longitudinal guideway 23 moved further to the rear. The engagement element 32 initially slides in which is substantially parallel to the longitudinal guide track 23 extending horizontal section 39 the slide tour 31 since in the rising starting section 11 the front guide rail 8th located gliders 13 no significant X or longitudinal movement of the lid 2 causes and thus the slide carrier 30 largely stationary in the X or longitudinal direction. The horizontal section 39 may, for example, in its course also lower a little more or have an S-shaped course, with which in the course of the front guide rail 8th moving skid 13 co.

When the engagement element 32 in a subsequent substantially vertically downwardly directed rear driving section 40 the slide tour 31 enters, the glider reaches 13 the upper horizontal level of the front guide rail 8th , That with the drive slide 22 moving engagement element 32 takes the scenery bearer 30 and with it the lid 2 along the front guide rail 8th With. At the same time the release lever 14 over the coupled coupling rod 27 moved.

In the in 5 shown position is the coupling rod 27 by means of the locking device 28 from the drive carriage 22 uncoupled and roof side z. B. in the recess 29 the guide rail 8th or on the latch hook 29 ' locked. This is the release lever 14 fixed to the rear guide rail 10 held. When the drive carriage 22 along its longitudinal track 23 continues to move backwards, he takes over his engagement element 32 the scenery bearer 30 and with it the lid 2 backwards with. The lid 2 is in front over the slider 13 on the front guide rails 8th and behind over the upper slider 17 of the release lever 14 led, whereby the cover 2 with its lid guide 18 relative to the upper slider 17 moved to the rear, while the release lever 14 remains stationary. A fully open position is in 6 shown.

When closing the lid 2 the movements described occur in opposite movement.

The place of fixing the coupling rod 27 on the roof or the front guide rail 8th or the position of the recess 29 for coupling / uncoupling and locking the coupling rod 27 as well as the length of the coupling rod 27 and thus the longitudinally blocked position of the deployment lever 14 is taking into account and depending on the available movement path and the provided support length between the front bearing device 7 and the rear storage facility 9 selectable and definable. When the front guide rail 8th in the dry area 33 and the rear guide rail 10 in the wet area 35 is arranged, represents the length of the roof opening 3 no restriction on the path of movement of the rear bearing device 9 or the release lever 14 dar. The lever 14 rather, in the area behind the roof opening 3 extending roof section 5 be slidably mounted and despite the partition 36 with the front bearing device 7 or the drive carriage 22 , which is also only in the dry area 33 be moved, connected or coupled.

The front guide rail 8th and rear guide rail 10 may each be attached to the roof structure or on roof side rails of the vehicle roof or they are parts of a frame assembly, the lid 2 stored and on the vehicle roof 1 is appropriate. The drive motor for adjusting the lid 2 is z. B. attached to a front or a rear cross member of the frame assembly.

The individual features disclosed in the description and on the basis of the exemplary embodiment can be combined with the subject matter of the invention in its general form in any technically expedient arrangements and configurations.
